OTPMK and secure boot

Question asked by Siles on May 6, 2016

Hi everyone,

I'm trying to achieve secure boot on a LS1021a board. Every document I read on the subject says to program the OTPMK and SRKHR fuses at the same time, prior to triggering the secure boot. From what I understand in the documentation, only the SRKHR is used during the secure boot.

 

Can I achieve secure boot by only programming the SRKHR fuses, and leave the OTPMK for later ?

 

Best,

Vincent
